The bill establishes a child tax credit for resident individual taxpayers in Kansas, effective for tax year 2025 and beyond. The credit amount varies based on the taxpayer's adjusted gross income, with a maximum credit of $600 for those earning up to $25,000, decreasing incrementally to $25 for those earning over $350,000. Married individuals filing separately can claim half the credit amount they would have received if filing jointly. Additionally, the bill includes provisions for annual adjustments to the credit amounts based on cost-of-living increases and mandates that the Secretary of Revenue compile and submit an annual report detailing the credit's impact.

The bill defines a "qualifying child" and outlines the criteria for eligibility, including age, residency, and support requirements. It also specifies that only one taxpayer can claim a qualifying child per tax year. If the credit exceeds the taxpayer's income tax liability, the excess will be refunded. The provisions of this section are intended to supplement the existing Kansas income tax act.
